Lately, I cannot make Firefox the default browser. When I start Firefox, it "knows" it is not the default browsers and a requester come up asking if I want to make it so. I click to do so, but it does not work. I have to go to Control Panel/Default Programs and do it there.

I'm not sure if this is related, but I have also had login problems on a couple of sites. If I click on login, the page I am on simply refreshes and I am not redirected to the login page. IE and Chrome work perfectly on these pages.

Flashplayer updated today, and as is my custom, I went through my three browsers making each one the default before updating. After I finished, Firefox again would not let me set it as default from within the program. I had to do it through the Control Panel Default Programs option. VERY annoying..... Chrome and IE had no problems allowing themselves to be set as default from within the program.
